bloke_zero is right - error 1009 happens when the player cannot find the audio plug-in, which is a necessary component to playback mp3 files.

Make sure you have the audio plug-in in your FlowPlayer3 shared directory.

You can also check your site log (Administer > Reports > Recent log entries) to look for page not found errors. This will show you what file the player is unable to find. This will also help you check that you have the right version of the audio plug-in file.

I've added this to FAQ page for future reference as this is a common step that gets missed when configuring FlowPlayer 3.

If the above fixes the problem please change status on this thread to fixed.

I still have the same problem. I looked in the logs and, yes, I had the control.swf missing. Then I put it inside the right directory and now I don't get any error logs but I still get the #1009 when opening the flowplayer with a flv video.
